nder another day's sun the hot asphalt was again taking the print of the tires of Rawson's old car. But this time, when he came to the almost obliterated marks that led through the sand toward distant mountains, he stopped, partially deflated the tires to give them a grip on the sand, and swung off.
"A fool, kid trick," he admitted to himself, "but I want to see the place. I'll see plenty of it before I'm through, but right now I've got to have a look; then I'll buckle down to work.
"Thermal Explorations, Limited!" The name rang triumphantly in his mind. "A million things to do—men, crews for the drills, derricks.... We'll have to truck in over this road; I'll lay a plank road over the sand. And water—we'll have to haul that, too, until we can sink a well. We'll find water under there somewhere. I've got to see the place...."
The black sides of the mountains were nearer: every outcropping rock was plainly volcanic, and great sweeping slopes were beds of ash and pumice; the wheel marks, where they showed at all, wound off and into a canyon hidden in the tremendous hills that thrust themselves abruptly from the desert floor.
The mountains themselves towered hugely at closer range, but the road that Rawson followed climbed through them without traversing the highest slopes. It was scarcely more than a trail, barely wide enough for the car at times, but boulder-filled gullies showed where the hands of men had worked to build it.
e came at last into the open where a shoulder of rock bent the road outward above a sea of sand far below. And now the mountains showed their circular arrangement—a great ring, twenty miles across. At one side were three conical peaks, unmistakable craters, whose scarred sides were smothered under ash and sand that had rained down from their shattered tops in ages past. Yet, so hot they were, so clear-cut the irregularly rimmed cups at their tops, that they seemed to have pushed themselves up through the earth in that very instant. At their bases were signs of human habitation—broken walls, scattered stone buildings whose empty windows gaped blackly. This was all that remained of New Rhyolite.
Rawson looked at the "ghost town" which had never failed to interest him, but he gave no thought now to the hardy prospectors who had built it or to the vein of gold that had failed them. His searching eyes came back to the fiery pit, the Tonah Basin, a vast cauldron of sand and ash—great sweeps of yellow and gray and darker brown into which the sun was pouring its rays with burning-glass fierceness.
But to Rawson, there was more than the eye could see. He was picturing a great powerhouse, steel derricks, capped pipes that led off to whirring turbines, generators, strings of cables stretching out on steel supports into the distance, a wireless transmitter—and all of this the result of his own vision, of the stream he would bring from deep in the earth!
